A pregnant woman was taken to hospital after her car crashed into a pole at a pedestrian crossing and knocked it down as she turned a corner.
The driver, thought to be in her twenties, and another woman were treated at the Northern General Hospital.
Their red Mazda 3 car was stuck on the pole - used for a pedestrian crossing button - at the corner of busy Granville Road and Shrewsbury Road in Sheffield city centre for hours before it could be recovered.
Harry Rolston, a salesman at the nearby Subaru car dealership, said: “It was a woman who went straight over the pedestrian crossing.
“There should be a sign at the corner really, because you can’t see around it.
“We only realised what had happened when all the police arrived.”
The collision happened at around 12noon yesterday.
Workmen from council highways contractor Amey were waiting at the scene to replace the pole once the car had been removed.
A police spokesman said the extent of the women’s injuries was not known.
